[0002] The octane number of gasoline is often required to be tested during the gasoline production process. The octane number of gasoline is a digital indicator to measure the anti-knock combustion ability of gasoline in the cylinder. A high value indicates good anti-knock performance. The detection of the octane number of gasoline requires sampling of gasoline. Gasoline sampling is mostly achieved by the principle of negative pressure suction.
